Thank you so so much, everyone! The reptile community online has been such a huge help and inspirations since I first became interested in owning a snake this time last year. I'm going to do everything I can to be the best snake-mum I can!
He is a pretty decent size - he's 840g, ~14 months old. He's apparently a well established eater at the minute, so hopefully the stress of his move won't put him off his food!
